Morning Star Relay Driver

Morningstar’s Relay Driver is a logic module which provides high level system control functions such as high/low voltage alarms, load control and generator start. The product controls four independent relay driver outputs by reading digital data inputs from Morningstar’s TriStar controller or by reading battery voltage when used in systems with other controllers.

Typical Functions:

High and Low Alarm Contacts

for Industrial Applications

Load Control Including High

Power Applications (pumps

and large motors)

Temperature Controlled Settings

for Battery Fans or Cooling Vents

Generator Start Functions

Auxiliary ACBackup Charge Control

Data Control Input Options:

Connected to a TriStar Controller:

Battery voltage, charge/load current, battery temperature,

TriStar heatsink temperature, PWM duty cycle, PV/load voltage,

and all TriStar alarms or faults.

Used in Systems with Other Controllers:

Battery voltage, Relay

Key Features and Benefits:

Cost Effective:

The four channels provide up to four high level system control functions

at a lower cost compared to other alarm and generator start packages.

High Reliability:

Each channel has complete electronic protections for high reliability.

Flexibility:

The system designer may choose the exact relay needed for each

application including a wide range of current ratings and solid state,

mechanical or mercury displacement relays.

Fully Programmable:

It is easy to program the Relay Driver with the included PC software via
